To find the axis of symmetry you use the formula: x=-b/2a
The axis of symmetry is also the x point of the vertex so to find the y point you just plug in the axis of symmetry in for x to find the y point.
42°
Step-by-step explanation:
(Angles in linear pair)
(Angle sum postulate of a triangle)
(corresponding angles)
(vertical angles)
All you got to do is times both of the numbers and then you get your answer and if you don't know use a calculator it's really easy
Answer:
corresponding angle
Step-by-step explanation:
x = y
